Paperback. Condizione: New. Print on Demand. This book examines human impact on the Chisos Basin and adjacent lands within Big Bend National Park. The author evaluates the impact of camping, roads, horse usage, and other activities on the area's vegetation, after first considering the geologic and climatologic factors that influence its natural condition. Comparing present vegetation on various substrates and exposures to a hypothetical pristine state, the author discusses themes of denudation, alteration, and creation, demonstrating how human use can both harm and improve an ecosystem. The book also discusses the impact of human activity on Boot Canyon, Oak Creek Canyon, and Cattail Falls. It concludes with recommendations for rehabilitating the basin and mitigating future environmental impact, emphasizing the need to balance human enjoyment with the preservation of the park's natural beauty. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
